    onion-grater: retry connecting to the real control port. · f74cec4d

    This should not be necessary and is just placed here as a workaround
    until I can figure out the real issue (bug in onion-grater? bug in
    When working on the Tor Browser 9.0 migration there were issues with
    Tor Launcher. It starts and does its initial connection to the control
    port where it successfully fetches CONFs etc. When clicking "Connect"
    it successfully sends a few more things and disconnects, only to
    reconnect immediately later (due to some implementation detail in Tor
    Launcher). This reconnection fails:
        /usr/local/lib/tor-browser/firefox-unconfined (pid: 8865, user: tor-launcher, port: 57472, filter: tor-launcher): -> SAVECONF
        /usr/local/lib/tor-browser/firefox-unconfined (pid: 8865, user: tor-launcher, port: 57472, filter: tor-launcher) disconnected: Client closed its socket
        [ Here comes the reconnect: ]
        /usr/local/lib/tor-browser/firefox-unconfined (pid: 8865, user: tor-launcher, port: 57476, filter: tor-launcher) connected: loaded filter: tor-launcher
        Final rules: [...]
        Unable to connect to tor. Maybe it's running without a ControlPort?
        /usr/local/lib/tor-browser/firefox-unconfined (pid: 8865, user: tor-launcher, port: 57476, filter: tor-launcher) disconnected: client quit
        Exception happened during processing of request from ('', 57476)
        Traceback (most recent call last):

          File "/usr/lib/python3/dist-packages/stem/connection.py", line 803, in authenticate_cookie
            auth_response = _msg(controller, msg)
          File "/usr/lib/python3/dist-packages/stem/connection.py", line 1055, in _msg
            return controller.msg(message)
        AttributeError: 'NoneType' object has no attribute 'msg'
    But if we just connect yet again, it works, hence the workaround.
